Since Johannes Kepler's supernova was spotted in 1604, astronomershaven't witnessed one in our own galaxy.(自1604年开普勒发现一颗超新星以来，天文学家便再也没有在我们的银河系发现这种天体。)
The star then explodes in a so-called Type II supernova.(这颗恒星随后发生爆炸，成为II型超新星。)
Then those findings were later reviewed, the old location pinpointed, and the remnants of a supernova found.(这些记录被后人加以分析，找到了准确的位置，并发现了一颗超新星的残骸。)
Views of the developing supernova are beinguploaded here.(在这个地址正不断上传着这颗不断演化的超新星的照片。)
In particular, consider Supernova 1987a.(特别是超新星1987a。)
The brightest supernova in 400 years resembles a cosmic string of pearls.(最亮的超新星在400年内类似于一串宇宙珍珠。)
For many it could be a once in a lifetime chance to see a supernova blossom and then fade before their eyes.(观看一颗超新星在自己眼前爆炸然后逐渐消失，这对于很多人来说，都恐怕是一辈子只能有一次的经历。)
Most recently, those crazy scientists have even recreated a 'supernova' in a test tube!(最近，那些疯狂的科学家们甚至在试管里搞出一个“超新星”！)
It is the remnant of a supernova that was recorded by Chinese and Arab astronomers in 1054.(早在1054年，中国和阿拉伯天文学家就有关于它是超新星残余的记载。)
It might sound weird, but glycerol and water make great analogs for the exploding cloud of supernova matter!(这听起来可能很奇怪，但甘油和水是超新星物质爆发云团的极好的近似物。)
